Harvard doctor offers an effective method to fall asleep faster: “Scientifically proven”

Few things are more frustrating than lying awake in bed, staring at the ceiling, knowing you need to be up early—but sleep just won’t come. It’s a nightly struggle for millions, and while some turn to medications or herbal remedies, one surprisingly simple trick is gaining traction thanks to Harvard physician Dr. Trisha Pasricha.

Her advice? Wear socks to bed.

“Wearing socks to sleep is an easy, natural way to fall asleep faster,” says Dr. Pasricha. “It’s scientifically proven that warming your feet triggers drowsiness and can be just as effective as many over-the-counter sleep aids.”

The tip, shared by The Washington Post on Instagram, has sparked widespread interest for its simplicity and effectiveness. According to Dr. Pasricha, warming your feet isn’t just cozy—it activates a physiological response that helps your body wind down.

Decades of research support the practice. “The idea is that heat dilates the blood vessels in your skin, which helps warm the body,” she explains. That subtle shift in temperature signals your brain that it’s time to sleep.

For those looking to avoid medication and explore natural sleep solutions, this method offers a low-effort, science-backed option. As Dr. Pasricha emphasizes, small changes in your nightly routine can make a big difference in your sleep quality.
